 #
 # Interactive script for sending a collection of Mercurial changesets
 # as a series of patch emails.
 #
 # The series is started off with a "[PATCH 0 of N]" introduction,
 # which describes the series as a whole.
 #
 # Each patch email has a Subject line of "[PATCH M of N] ...", using
 # the first line of the changeset description as the subject text.
 # The message contains two or three body parts:
 #
 #   The remainder of the changeset description.
 #
 #   [Optional] If the diffstat program is installed, the result of
 #   running diffstat on the patch.
 #
 #   The patch itself, as generated by "hg export".
 #
 # Each message refers to all of its predecessors using the In-Reply-To
 # and References headers, so they will show up as a sequence in
 # threaded mail and news readers, and in mail archives.
 #
 # For each changeset, you will be prompted with a diffstat summary and
 # the changeset summary, so you can be sure you are sending the right
 # changes.
 #
 # It is best to run this script with the "-n" (test only) flag before
 # firing it up "for real", in which case it will use your pager to
 # display each of the messages that it would send.
 #
 # To configure a default mail host, add a section like this to your
 # hgrc file:
 #
 # [smtp]
 # host = my_mail_host
 # port = 1025
 #
 # To configure other defaults, add a section like this to your hgrc
 # file:
 #
 # [patchbomb]
 # from = My Name <my@email>
 # to = recipient1, recipient2, ...
 # cc = cc1, cc2, ...
